Since then the newer chipsets have also addressed the early issues there as well. As for which edition either works while the Home edition tends to be a little more media player orientated while Pro is loaded more for network support.

Both use the exact same NT core and shell for the most part making them both software compatible. I ran identical things on both along with Vista on the last build with Pro left behind and Home still on for older Vidso capture/editing reasons. Both will see SP3 go right on as well while the MCE edition? Some are reporting a few problems with the later upgrade to Pro there.
